Abstract
Investigation of the effect of co-dried fish silage (CFS) in poultry feed on performance of Broiler and Giriraja chick, and also comparison of the nutritional quality of prepared poultry feed with commercial feed was done. The sensory evaluation of meat was carried to check the eating quality. The silage was prepared from reef cod (Epinephalus diacanthus) fish waste using 3.5 % (w/v) formic acid and propionic acid mixture (1:1 ratio). The biochemical parameters such as PV, TBARS, TVBN and TMA of the fish silage was estimated as 8.97 ± 0.09 meq. O2/kg of fat, 3.93 ± 0.001 mg malondialdehyde /kg of fat, 48.25 ± 0.09 mg /100 g and 14.28 ± 0.06 mg /100 g respectively. The silage was mixed with crushed corn powder in the ratio of 85:15 (CFS had 39.51 % protein). 120 numbers of Broiler and Giriraja chicks were randomly assigned to 4 dietary treatments (C – Control diet, T1 – Diet with 5% CFS, T2 – Diet with 10% CFS, and T3 – Diet with 15% CFS). Average weekly body weight gain, feed intake and FCR were recorded. At the end of the experiment (6 week) overall FCR, BPEF and livability was also calculated. Later, 10 birds from each group were randomly taken and sacrificed by approved Kosher method to study the meat quality and growth of internal organs. Significant differences were found with weekly feed intake, body weight gain, FCR in Broiler and Giriraja chicks. The dressing yield % was higher in Broiler’s T1 group and Giriraja’s T2 group. The treatment group -T1 (5% CFS) of Broiler and Giriraja chicks had higher BPEF than the other groups. The prepared diets containing CFS showed better storage stability (>2 months) than other diets with lower values of PV, FFA, TPC, fungal count. The present study was concluded that the 10 % CFS could be used as un-conventional protein source for poultry rearing without affecting the growth performance of chicks and eating quality of meat.
